A hydrogen production system with controllable aluminum-alkali reaction

Abstract

The invention discloses a hydrogen production system with controllable aluminum-alkali reaction, which includes a water injection device, a reaction device and a collection device connected in sequence through pipelines. The reaction device includes a frame, a reaction bottle and a turning mechanism. It is installed on the rack in an overturning motion. There is a permeable partition in the reaction bottle to separate the reaction bottle into a left chamber for storing aluminum powder and a right chamber for storing alkali materials. The water injection device passes through the pipeline and the right chamber. Connected, and the collection device is connected with the left chamber through the pipeline; during the gas production operation, the turning mechanism drives the reaction bottle to be in an upright state or the right chamber is in a non-upright state; when the gas production is stopped, the turning mechanism drives the reaction bottle to quickly turn to the left The non-erect state of the chamber on top. The invention has the advantages of a simple and compact structure, high integration, low energy consumption, fast hydrogen production reaction, and a controllable aluminum-alkali reaction hydrogen production system that can realize fast start-stop control of the aluminum-alkali reaction at any time.

Description

technical field [0001] The invention mainly relates to the field of hydrogen production equipment, in particular to a hydrogen production system with controllable aluminum-alkali reaction. Background technique [0002] As a renewable energy, hydrogen is not only used in new energy vehicles, but also widely used in many fields such as medical care, meteorology, entertainment and so on. However, the existing aluminum-alkali reaction hydrogen production equipment often has poor controllability and cannot guarantee the purity of the hydrogen produced. Specifically, there are the following technical problems: [0003] One is that the current aluminum-alkali reaction hydrogen production equipment lacks a buffer device in the system, which may easily cause excessive instantaneous pressure during hydrogen production and cause pipeline leakage. [0004] The second is that the current aluminum-alkali reaction hydrogen production equipment cannot discharge the residual air in various...

AI Technical Summary

Problems solved by technology

[0003] One is that the current aluminum-alkali reaction hydrogen production equipment lacks a buffer device in the system, which may easily cause excessive instantaneous pressure during hydrogen production, causing pipeline leakage

[0004] Second, the current aluminum-alkali reaction hydrogen production equipment cannot discharge the residual air in various devices and pipelines, resulting in insufficient hydrogen purity.

[0005] Third, the reaction time of the current aluminum-alkali reaction hydrogen production system is slow

For example, some use aluminum rods to react with alkaline water, which makes the contact area of ​​aluminum alkali limited, which greatly affects the efficiency of hydrogen production by aluminum alkali

[0006] Fourth, the current aluminum-alkali reaction hydrogen production system has poor control effect and cannot effectively control the start and stop of the hydrogen production reaction, that is, it cannot control the aluminum-alkali hydrogen production reaction at any time and quickly. When the system stops collecting operations, its aluminum-alkali If it cannot be separated in time, it will still react for a period of time and produce hydrogen, which not only greatly causes resource consumption and waste, but also easily leads to safety accidents

At the same time, the current aluminum-alkali reaction hydrogen production system cannot be used immediately when it is stopped, or stopped when it is used, the system starts slowly, the work efficiency is low, and the operation mode is not flexible.
